I could see it happening but did the children not wake up and cry due to the discomfort? If they cried, why didn’t the parents respond? My first thought was CO poisoning, as well. Strange case.
I agree. If it was just heat, you would think those boys would have been making a ruckus at the first sign of discomfort. And if they are anything like mine, they can make alot of noise.
Plus, how hot could it have gotten overnight? They found them at 8:30am.
Regardless, a horrible tragedy...
